Xiaobaitu, what should we do? Please help

My hu*****and was Eb1b 485 pending from a university.
Time line:
9,2003 applied 140
8,2004 140 approval
10,2004 applied 485
3,2005 current

We have not heart any information about it. When I call INS I just get our case resuming from automatic voice system.

My hu*****and changed his job from university to a small company on march this year. Now his group of this small company sold to a big company. What should we do? Do we give a notice to INS? Please advice.

Thanks a lot
